Raw sewage overflow is a serious problem that occurs when storms hit New York City and floods fill our harbors with billions of gallons of disgusting pollutants. Lately these storm surges have been overpowering the dated prevention methods that are currently in place, but the Environmental Protection Department has as new solution – inflatable dams. The innovative new devices have been installed in the Brooklyn neighborhoods of Williamsburg and Red Hook and work by inflating when storm surges are high, thereby controlling waste water before it can reach the harbor.
